i To all whom it may concern:

l Be it known that I, ALBERT Kruurzssnesnjmanu;

facturer, residing at' Holzhausen, near Leipzig, vin the'.` Kingdom of Saxony, in the GermanEmpire, a subject Y of the Austrian Emperor, have. invented certain'new and us'eful Improvements in Dust-Collectors, of which. the following is a full, clear, and exact specification,

and for which I have applied for alpatent in Germany,

on theth of March, 1905; furth'er I have received a 'patent in lEngland, N o. 5558/ 1905, the date of application being Athe, 6th oMarch, 1905;' and further I have applied for a patent in France on theSd of November, 1905.

My inve'ntion relates to and has paratus for separating dust from currents of air or other gases and particularly to apparatus for recovering the waste products, in the'cetamic industry wherein colors often of considerable value lare sprayed on 'to the artifor' its object an apcles manufactured.

When working with dust collectors of the type in which perforated plates are arranged in a box crease, various requirements must be complied with in order to obtain efcient working. For example it ,is necessary to so set in the perforated plates that they. are not vertical but horizontal. Further it is advisable to arrange scraper's so thatwhen the pla es are withdrawn the d'ust attaching thereto is not dig-n o'nt with them, but is removed by the said scrapers and falls inside the apparatus. While by the vertical position of the perforated plates the dust falls to the bottom of the case of the apparatus and consequently cannot be very easily co1- lectcd together, -by the horizontal arrangement of the g plates there is the advantage that the dust scraped off j all collects on the lowest plate after the' upper plates have been removed one after the other. vThe last plate may be unperorated so that the dust cannot fall through and is collected on it. It is further advisable' that the case in which the plates are tted should be transparent, for example made of glass, so that one can perceive at a glance if the plates ought to be changed. m

The accompanying drawings illustrate one fr.' rmv of an apparatus embodying my invention wherein: r

Figure l. is a verticalpsecton as seen from the side from which the plates are withdrawn. Fig. 2: is a vertical section from the side at right angles to that from which the plates aredrawn out. Fig. 3. is an outside elevation showing one of the two lids, hereinafter refer-red to, :partially removed. Fig. 4. is a' horizontal'. section. Fig. 5 is a sectional view of a modication.

Similar lettersof reference refer to similar parts in all views.` j

1n the example illustrated a is the case or box proper, b is the' Working opening preferably having a small oa'rd or platform c, on which th i dust can ,be placed, or .it

source dust in lany suitable-manner. Atthe bottom it is'desired to change Y of the case a, a pipe d is arranged and connected with an exhauster or other device for withdrawing the air.y The perforated plates 'e are arranged in the case ain a 'lttingf so that they can vsepaz'atelyfas will be seenfrom the drawing the fitting f is in the form of a botto'mless drawer. lhelwhole fitting f with all the plates can alsogbe bodily withdrawn. The fitting is closed on one sideby a lid or cover g which contains a division for each plate. ther the cover g has scrapcrs h fitted to it. Thesefpreferably consist of strips of sheet steel which press against the plates and when the latter are withdrawn from the case they remove any dust clinging to ther-n..V The lid g can be litted to the c such as by hooks or the like.

It proves specially suitable fol` ire purposeto make the perforated plates e of aluminium. the plates in being scraped should suffer slight dam age or deterioration and thereby'r come by chance into the collectl these parts can do absolutely no-damage. While'bit Vof iron or other material producen discoloration in the burning of the colors, as they have colored combinations, this is. not the c ticlos of aluminium, since aluminiunrjs a metal, the combinations with which are colorless. A When the apparatus is working, the tting f is put into the apparatus. The air laden lwith dust as it passs through the apparatus deposits its dust on the 85 ery easy when the plates are full plates e and so it is v to withdrawV them one by one until all the dust is col lected on the last plate, o'r the whole fitting with.al1 the plates can be withdrawn at once, so that a fresh fitting f with other moment. This opera handles z' fitted to the ing all the plates con of the present invention, and of especial-importance for a case for instance, when the appa the ceramic industry where, when paint .issprayed tion is very simple ow'lng to the colors and it is often absolutely necessary to keep the Up to the present it hasbeen nece state apparatus for each color. only possible in large undertakingsand occasioned 'a greatloss of time. l v Al r In order to obtain a complete closing of the appa- -ratus, a secondchver k'is provided, which can be tened totheprojecting edge of the inner cover g a h rngevz and, hooks m. 1f it is intended to wand individual plates from i all the pla bt the whole '1: is x et rexwved can be withdrawn by the handles e'.

In this case if parts ottherplates edrdust, even then,

plates can be substituted in a lid g. The possibility of chabg- .A stitutes an important 'advantage tatus is usedl in by an air sprayer, it is often necessary to change the colors, some of which are very valuablg, separate? ssary to have@ sep-l .1;00 lThis .was however Y. the apparatus,l cover k is" opened and the separate platesremoved. If however tes at once, the cover "i alrcadymentioned, therapiditykoecurity is considerably' increisetl by making the case 'o gloss. Naturally in this case the'iittng must also he made of gloss or, as already referred to, consist of only a 'set of divisions orgrooves which serve os guides ior the plates e, or when thecover serves use support for the' plates, Aitcon be entirely dispensed with.

The advantages of the-present iizlventionV other than th'ose already referred to, consist in the exceptionally Vorhnge:i

The use of special distributors and ventilators, as is usual with euch apparatus for distributing the a'ir currentr over the whole suriacepc'an be dispensed with. This vertical arrangement also takes up much less space, es the apparatus whatever the number oi plates used has only the saniie `cross section. i

what I claim and desire to `secure by Letters Patent s:- 1. A dust collector' ot the type described, comprising in combination n casing,` having an nir-inlet openingat its ripper end; u bottomless drawer with n, plurality of horizontaligmoves on its side walls und n plurality of correspending slot like openings in its front wall, 'n'piurality .ot seperately removable perforated horlzontil plates en- 'gaglng in sold grooves und odtpted to bc withdrawn through suiu slot like openings, strips of sheet steel at tricked to ssidfront walls with their freeedges ln contact with the plates und adopted ,to scrape sold plates during their removal2 und a* detachable ,cover adapted to cover hermeticelly the exterior ot said front Wall.
